A novel ratiometric and colorimetric probe for rapid and ultrasensitive detection of nitrite in water based on an Acenaphtho[1,2-d] imidazole derivative

An efficient ratiometric fluorescence and colorimetric dual-mode probe for convenient determination of nitrite in real samples and E. coli

“…7 Therefore, it is of great significance to develop effective and convenient nitrite detection methods in food safety, environmental monitoring, clinical diagnosis of diseases, and many other areas. To date, various analysis techniques have been exploited for the detection of NO 2 − , 8 such as spectroscopic and electrochemical analysis, 9–12 capillary electrophoresis 13 and chromatography. 14–16 Among them, spectroscopic methods based on the Griess diazo-coupling reaction, especially fluorescent probe technology have attracted extensive attention 17–24 due to the high selectivity and sensitivity, fast response, low background interference and high spatiotemporal resolution for biological applications.…”

Rapid-Response Nitrite Probes: Intramolecular Griess Reaction for Nitrite Detection at Picogram Level

“…However, the lack of availability of ion chromatography instruments at commercial manufacturing sites can be a hurdle to quickly assaying nitrite content in materials received for drug product manufacture. Therefore, not only HPLC and GC methods but alternative methods that utilize the derivatization reaction (Griess reaction) or other detector molecules − have been widely reported. − There are many different methodologies of the Griess reaction, and there are several commercially available Griess reagent kits that often come as a premixed acidic solution. These reagents are comprised of two reaction components, sulfanilamide and N -1-naphthylethylenediamine.…”

Ratiometric colorimetric detection of nitrite using CoMnO3 nanofibers as an oxidase-like enzyme to induce diazotization reaction

“…14 Ratiometric colorimetry is a more attractive route for research since it can improve accuracy and reproducibility, sensitivity, and anti-interference capabilities in comparison to single-wavelength spectrophotometry. 15 Zhang et al developed a ratiometric colorimetric sensing platform for nitrite detection in food and aquatic systems by catalyzing TMB oxidation using CoOOH nanosheets (CoOOH NSs). 16 Liu et al employed iron monoatomic catalysts (Fe SACs) as catalysts through redox and diazotization reactions to establish sensitive and selective colorimetric and paper detection approach for nitrite.…”
